If you see square waves in the ocean, it is a sign that dangerous rip currents are present. These powerful currents can quickly pull swimmers out to sea, making it difficult for them to return to shore. If you notice square waves forming, it is important to get out of the water immediately and alert others of the potential danger. It is always best to swim at beaches with lifeguards present to ensure your safety in case of rip currents or other hazardous conditions.
